| Exercise Training Intervention | Behavioral | 5.1. The behavioral ET and HLE interventions will be delivered over 12 weeks. Before starting the study, men will be asked to attend one (1) in-person small group orientation to provide an overview of each intervention arm, familiarize them with web-based and smartphone applications or hard copy manuals for delivery of intervention content, exercise logs, resistance bands, and equipment for strength training. |
| Measure | Description | Time Frame |
|---|---|---|
| Change from baseline in maximal exercise capacity (VO2 peak) at 12 weeks | Exercise capacity will be measured by the maximal volume of oxygen utilization (VO2 peak) during a supine graded cardiopulmonary exercise test done in conjunction with cardiac magnetic resonance (exeCMR+CPET). VO2 will be measured in both relative (ml/kg/minute) and absolute (L/minute) terms. | Baseline, 12 weeks, and 24 weeks |
| Change from baseline in sub-maximal exercise capacity (6MWD) at 12 weeks | The distance walked in a sub-maximal 6-minute walk test (6MWD). 6MWD will be reported as meters walked (m). | Baseline, 12 weeks, and 24 weeks |
| Measure | Description | Time Frame |
|---|---|---|
| Stroke Volume (SV) as a cardiac determinant of exercise capacity among men undergoing ADT following 12 weeks of ET vs HLE controls. | By measuring resting and exercise -associated left ventricular (LV) end-diastolic (EDV) and end-systolic volumes (ESV) we will calculate stroke volume (SV) in milliliters/beat (ml). SV = EDV - ESV | Baseline, 12 weeks |

| Healthy Living Education | Behavioral | During the initial 12 weeks of the study, men randomized to the HLE group will receive educational modules delivered remotely (or manual and telephone call) in a group-based setting to approximately match contact frequency and structure with the ET arm. |
|
| Left ventricular ejection fraction (LVEF) as a cardiac determinant of exercise capacity among men undergoing ADT following 12 weeks of ET vs HLE controls. | By measuring resting and exercise-associated stroke volumes (SV) as a proportion of end-diastolic volumes (EDV) we will calculate left ventricular ejection fraction (%). LVEF = SV/EDV | Baseline, 12 weeks |
| Cardiac output (CO) as a cardiac determinant of exercise capacity among men undergoing ADT following 12 weeks of ET vs HLE controls. | By measuring resting and exercise-associated stroke volume (SV) and the heart rate (HR) in conjunction with image acquisition we will calculate cardiac output in liters per minute (L/min). CO = SV x HR | Baseline, 12 weeks |
| Arterial-venous oxygen (a-vO2) difference as a musculoskeletal determinant of exercise capacity among men undergoing ADT following 12 weeks of ET vs HLE controls. | From the exercise tests we will calculate a-vO2 difference using the FICK equation. The difference in oxygen saturation between the venous circulation and the arterial circulation will be reported in milliliters (ml) and also expressed as ml/100ml of blood (%) a-vO2 = VO2 / CO | Baseline, 12 weeks |
| Change in lean body mass | We will conduct body composition assessments using bioelectrical impedance analysis (BIA) and a Dual Energy X-Ray Absorptiometry (DXA) scan. We will use dual X-ray absorptiometry (DEXA) to assess whole body composition for lean body mass. Lean body mass will be reported as kilograms (kg) | Baseline, 12 weeks |
| Change in fat mass | We will conduct body composition assessments using bioelectrical impedance analysis (BIA) and a Dual Energy X-Ray Absorptiometry (DXA) scan. We will use dual X-ray absorptiometry (DEXA) to assess whole body composition for fat mass as well as distribution patterns of adiposity, e.g., visceral adipose tissue. Fat mass and visceral fat mass will be reported in kilograms (kg) and body fat percentage will be reported as fat mass / body mass (%) | Baseline, 12 weeks |
| Neighborhood Environment & Walkability Survey (NEWS-A) | NEWS-A is a validated self-reported survey used to assess factors that are correlates or determinants of participants ability to engage in physical activity in their neighborhoods.
